BAND-FASTENING.

SPECIFICATION forming part of Letters Patent No. 759,328, dated May 10,1904,

Application filed March 7, 1904. Serial No. 196,993. (No model.)

To all whom it may concern:

Be it known that I, EMIL C. TEOKTONIUS, a citizen of the United States,residing at Racine, in the county of Racine and State o-fWis-' ing hadto the accompanying drawings, forming a part thereof.

The improvement constituting my present invention relates moreparticularly to large fastenings for heavy flat bands. Its main objectsare to prevent breaking the heads by tightening the wedges therein andat the same time securely fasten the bands in the head, so that theycannot slip, without riveting, accurately fitting, or exactly cutting tolength.

It consists in certain novel features of construction and the peculiararrangement of parts hereinafter particularly described, and defined inthe claims.

In the accompanying drawings like letters designate the same parts inthe several figures.

Figure 1 is a side view of a band-fastening embodying my invention, themember of the fastening to the left being shown in longitudinal sectionin a plane perpendicular to the band and the member to the right inelevation. Fig. 2 is aview of the fastening, partly in longitudinalsection in a plane parallel with Fig. 3 is aview of the outer end of oneof the heads as seen from the right with reference toFigs. 1 and 2, andFig. 4 is a view like Fig. 1 of a modified form of the fastening.-

Referring to Figs. 1 to 3, inclusive, the fastening is composedgenerally of two heads a a, adj ustably connected by bolts 5 b. Eachhead is formed with a tapering longitudinal opening through it for thepassage of one end of the band 0 and for the reception of a wedge (Z,fitted to clamp and secure the band therein. It is also formed on eachside with a longitudinal sleeve for connecting it with the companionhead by the tie bolts 7), which are threaded at the ends and providedwith nuts f. An internal shoulder or abutment g is formed across theopening through each head on the jected.

outer wall of the head, and the wedge (Z is iitted in the head so thatwhen brought into place snugly against the band it will abut at itssmaller end against said shoulder, thereby preventing breaking oroverstraining the head by forcing the wedge too tightly into it. Thewedge is fitted so that it will grip the band with some force in thehead before it is brought to a bearing against said shoulder. To insureagainst the band slipping in the head after the wedge is insertedinplace, the end of the band is bent outward, as shown in Fig. 1, next tothe larger end of the wedge, so that when strain is put upon the band bytightening the nuts on the bolts bthe heads cannot slip on the bandwithout straightening the bends therein, and this with thick heavy bandscan hardly occur with any strain to which they would ordinarily be sub-However, to insure against the bands being straightened and slipping inthe heads screws it may be threaded in the larger ends of the heads inposition to bear when adjusted against the inner face of the band, andthus retain the bends therein. To counteract the tendency of the endwisestrain on theband to tip the heads inward at their larger ends, they maybe formed, as shown, with lugs 71, adapted to bear upon the tie-bolts &.

In applying the fastening the band is cut to the required length, theends are passed through the heads a from the smaller toward the largerends of the openings, the wedges are then inserted and forced into placeagainst the shoulders g, the ends of the band are bent outward next tothe larger ends of the wedges, and if the screws it are employed theyare inserted or turned up into place. The band is then ready forapplication to a tank or other structure, around which it is placed, theheads being then connected by the bolts 6 and drawn together, so as toput the desired strain on the band by turning up the nuts f.

Referring to the modification shown in Fig. 4, the heads a are formedwith shoulders g on their inner instead of their outer walls, so thatthe ends of the band are clamped by the Wedges cl against the outerwalls of the heads. In this case the ends of the band are bent inwardlyover the larger ends of the wedges,

and the screws it are threaded in the outer walls of the heads inposition to prevent the straightening of the bends.

The principle and operation of both forms of the fastening areessentially the same.

IVith my improved construction as embodied in either of the forms hereindescribed the heads are held on the band and prevented from slippingthereon partly by the grip of the wedges and partly by the bends in theband at the larger ends of the wedges. Consequently the wedges do nothave to be forced as tightly into the heads to securely fasten them on aband as they would if the grip of the wedges were alone depended uponfor this purpose, and while they assist to hold the heads on the bandand serve to distribute the strain on the fastening through the headsthe shoulders g limit the extent to which the wedges can be forced intothe heads and hence their tendency to split them.

Various changes in minor details of construction and arrangement ofparts may be made without departing from the principle and intendedscope of the invention.

I claim- 1. In a band-fastening the combination of a head having atapering opening through it and an internal shoulder in the smaller endof said head, and awedge fitted to grip a band in said head and to abutat its smaller end against said shoulder, substantially as described.

2. In a band-fastening the combinationof a head having a taperinglongitudinal opening through it and an internal shoulder across thesmaller end of said opening, a wedge fitted in said opening to abut atits smaller end against said shoulder when forced into place against aband passing through the head, and one or more screws threaded in thelarger end of the head in position to prevent the straightening of aband bent next to the larger end of the wedge, substantially asdescribed.

3. In a band-fastening the combination of a head having a taperinglongitudinal opening through it and an internal shoulder across itsouter wall next to the smaller end of the opening and a wedge fitted toabut at the smaller end against said shoulder, when forced into place011 a band passing through the head, substantially as described.

4. In a band-fastening the combination of a head having a taperingopening through it and an internal shoulder across the smaller end ofsaid opening and a wedge fitted to abut at its smaller end against saidshoulder when forced into place on a band in said head, the band beingbent over the edge of the wedge at its larger end, substantially asdescribed.

5. In a band fastening a pair of heads each having a taperinglongitudinal opening through it and an internal shoulder across thesmaller end, bolts adjustably connecting said heads and wedges fitted toabut at their smaller ends against the shoulders in said heads whenforced into place on a band therein, substan tially as described.

6. In a band fastening a pair of heads each having a taperinglongitudinal opening through it with an internal shoulder across thesmaller end and longitudinal sleeves on the sides, tie-bolts secured insaid sleeves by nuts and adjustably connecting said heads, and wedgesfitted to abut at their smaller ends against the shoulders in said headswhen forced into place on a band therein, substantially as described.

7. In ,a band fastening a pair of heads each having a taperinglongitudinal opening through it and an internal transverse shoulderadjacent to the smaller end of the opening, wedges fitted to abut attheir smaller ends against said shoulders when brought into place on aband in the heads, and means for adjustably connecting the heads anddrawing the band taut around a tank or other structure, substantially asdescribed.

In witness whereof I hereto affix my signature in presence of twowitnesses.
